Creating a Javascript array from a VBScript Array

Hi

In my ASP page I am reading some data (page abstract text) into an array, arrText as follows:

<%
Dim rsAllSections
set rsAllSections = Server.CreateObject("ADODB.Recordset")
strSQL = "select ssecID, ssubsecID, ssecSection, ssubsecSubSection, iitemID, iitemAbstract from tvAllSecSub order by ssecHomepageOrder, xorder"
rsAllSections.Open strSQL, cnnConn, 1, 4

'Load the SubSections and abstracts into an array we can use later in JavaScript
dim arrNameAbs
arrNameAbs = rsAllSections.GetRows(,0,array("ssubsecSubSection","iitemAbstract", "ssecID", "ssubsecID"))

Dim strText, arrText
Dim a
For a = LBound(arrNameAbs,2) to UBound(arrNameAbs,2)
strText = strText & "<h1 class='mainHeading'>" & arrNameAbs(0,a) & "</h1><span class='smalltext'>" & arrNameAbs(1,a) & " <a href='subsection.asp?SectionID=" & arrNameAbs(2,a) & "&SubsectionID=" & arrNameAbs(3,a) & "'>More&raquo;</a></span>^"
Next
strText = Replace(strText, chr(10), "")
strText = Replace(strText, chr(13), "")
arrText = split(strText, "^")
%>

I write out a link for each record inb teh recordset created above.  When these links are rolled over, they call a Javascript function to change an iLayer and display the appropriate text from teh array.  The links look like this:

" <a href='subsection.asp?SectionID=2&SubsectionID=3' onMouseover='changetext(content[0])' class='smalllink'> "

My Javascript looks like this:

//========================================
//========================================
var content=new Array()
content[0]="<%=arrText(0)%>"
content[1]="<%=arrText(1)%>"
content[2]="<%=arrText(2)%>"

function regenerate()
{
      window.location.reload()
}

function regenerate2()
{
      if (document.layers)
      {
            appear()
            setTimeout("window.onresize=regenerate",450)
      }
}

function changetext(whichcontent)
{

      if (document.all||document.getElementById)
      {
            cross_el=document.getElementById? document.getElementById("descriptions"):document.all.descriptions
            cross_el.innerHTML='<font face="Verdana"><small>'+whichcontent+'<font></small>'
      }
      else if (document.layers)
      {
            document.d1.document.d2.document.write('<font face="Verdana"><small>'+whichcontent+'</small></font>')
            document.d1.document.d2.document.close()
      }
}

function appear()
{
      document.d1.visibility='show'
}

window.onload=regenerate2
//========================================
//========================================

I currently have to manually write additional " content[0]="<%=arrText(0)%>" " lines into the page to make the functionality work for all the links that are written onto the page.  THis means that I can't remove content using an admin interface without manually editing the page in question.  The url of the page is http://www.sabretele.com if you want to see what I'm on about.

I want to change the Javascript so that the "content" array is dynamically created, depending on the amount of rows returned from the database.  To do this, I want to populate the Javascript array "content" from the vbScript array "arrText" - how canb I do this?

Like this:


<script>
var content= [
<%  For a = 0 to UBound(arrText) %>
   "<%=arrText(a)%>" ,
<%  Next %>
   ""];
content.length--;
</script>

Hi Buddy

    Hope this helps you.

<%@ Language=VBScript %>
<%
      dim strValue
      strValue="A,B,C,D"
      arrText=split(strValue,",")
      
    str=" var Content = new Array(); "
    for i=0 to ubound(arrText)
            str = str & " Content["& i &"] ='"& arrText(i) &"';"
    next
   
%>
<script>
      // Javascipt array
      <%=str%> // Now your dynamic array is ready on the client side
            
      for (i=0;i<=Content.length-1;i++)
      {
            alert (Content[i]);
      }

</script>

Excellent answer by Zvonko - worked without any changes first time.  Thanks!


PradeepYadhav - your answer would have worked eventually I think, but needed some more work at my end & I don't have time to do it.  Sorry!
